Figure App.F.12.17.new A map showing the locations of spring season net samples by CalCOFI for use in analyses of abundance and trends in pelagic resources. Channel Islands National Marine Sanctuary region (red) includes CalCOFI stations inside and adjacent to CINMS; and Southern California Shelf (yellow) includes all CalCOFI stations over the shelf.

Figure App.F.12.19.anchovy A figure showing the relative abundance of northern anchovy (Engraulis mordax) collected during the spring around the Northern Channel Islands and the Southern California Shelf from 1978 - 2018. Data source: CalCOFI; Figure: A. Thompson/NOAA; Ben Best/EcoQuants

Relative abundance of key forage fish groups collected in net samples during spring CalCOFI cruises at sites in the Channel Islands National Marine Sanctuary (CINMS) and Southern California Shelf regions from 1978 to 2015. High energy taxa are Pacific sardines, northern anchovies, and Myctophids. Medium-energy taxa are Pacific hake, shortbelly rockfish, and sanddabs. Although sardine were completely absent in net samples from 2011 to 2014 in the CINMS region, comparison with samples collected in the larger Southern California Shelf region reveal that sardine were at very low abundance but not completely absent from the region.Hake
